Abstract: PROBLEM TO BE SOLVED: To provide improved aqueous-based (hydrophilic) thermally developable blends and materials including thermal conventional type silver ion reducing agents. SOLUTION: Thermally sensitive emulsions are provided which comprise (a) non-photosensitive reducible silver ion source, (b) a hydrophilic binder and (c) a non-crystalline reducing agent composition for the reducible silver ion, wherein the non-crystalline reducing agent composition includes two or more hindered phenol silver ion reducing agents.

Abstract: PROBLEM TO BE SOLVED: To lower the viscosity of a dispersion liquid without causing the problem of flocculation. SOLUTION: A hydrophobically capped oligomeric acrylamide or pyrrolidone is used as a dispersant for a hydrophobia material (a photographic additive such as a color coupler or a solid particulate dye) in an aqueous medium containing hydrophilic colloid. The preferred dispersant is a compound of formula (1) or (2). In the formulae (1) and (2), R, R1 and R2 are each selected from aliphatic hydrocarbyl, aryl-(aliphatic hydrocarbyl) and (aliphatic hydrocarbyl)- aryl; L is sulfur or a bonding group containing sulfur bonded to the group T; and T is a hydrophilic oligomer group obtained by oligomerizing one or more vinyl monomers each having an amido functionality.

Abstract: PROBLEM TO BE SOLVED: To provide an imaging element with resistivity for finger print, usual contamination and spilled matter. SOLUTION: A hardenable overcoat composition is applied over an image formed-element including a hardener that is introduced in the top layer of the image formed-element, and thereby the image with resistivity to finger print, usual contamination and spilled matter is formed.
